How Cow Dung Is Reinventing Plastics and Batteries

简介：

How Cow Dung Is Reinventing Plastics and Batteries. When we talk about the circular economy, we picture batteries stripped for their metals, factory floor scraps spun into sweaters, and agricultural waste transformed into biogas. We don’t picture mucking out the barn to collect material for surgical masks and food packaging. Waste may be used in new household products. It’s now possible to spin it into high‑tech, biodegradable plastics and textiles or use it as glue inside lithium battery electrodes. And as for the urine we send down the drain, it might someday help build our cities with better concrete. So, is this the next leap in sustainable design — or just a steaming pile of hype? And how close are we to building a cleaner, greener future from human and animal waste? 00:00 - Intro 02:22 - Cow Pie Bioplastics? 08:32 - Cow Pie Batteries? 09:47 - Pee Cement?
